FIELD: chemistry.
SUBSTANCE: invention relates to the technology of producing composite materials and methods of making housing elements of aircraft and space-rocket articles. Disclosed is a multilayer composite material which contains carbon-carbon layers and/or carbon-metal layers, joined by intermediate porous layers of carbonised carbon and comprising mainly carbon-carbon and carbon-metal parts of the composite material. Each of the carbon-carbon layers (K) on both sides of are coated with layers of carbonitride compounds of titanium and silicon (T), and inner intermediate porous layers of the carbonised carbon (E) contain copper-titanium layers (M). The carbon-metal part of the composite material contains aluminium-lithium (A) and magnesium-lithium layers (B,C,F), reinforced with carbon fibre (D), inner porous layers of carbonised carbon with copper-titanium surface layers, heated or cooled with inert gas using plasma heating or a gas-liquid medium based on an inert gas. The invention also discloses methods and devices for making a cowling, a cut off half-sphere, a shell and a half-shell using the disclosed composite material.
EFFECT: achieving good specific strength characteristics, brittle fracture resistance, heat resistance, erosion resistance, high reflecting and absorption capacity of the composite material, which significantly lowers weight, increases resistance to heat and meterorite effects, increases reliability of aerospace articles.
